<P>
A Clipped Object is one Object clipped by another.
The first Object is actually rendered; the second represents a region
to which the first Object is clipped.
The clipping Object is expected to be a closed convex surface.
The portion of the first Object that is within the clipping Object is
rendered.
If the clipping Object is not a closed convex surface, the results are
undefined.
The clipping is performed by the renderer during the rendering
process.
Thus clipping is provided as a data structure for representing the
Clipped Object to the renderer, rather than as an explicit
operation.
